# Fetch Ponyfill
|
||
|
|
|
||
|
|
> WHATWG `fetch` [ponyfill](https://ponyfill.com)
|
||
|
|
|
||
|
|
This module wraps the [github/fetch](https://github.com/github/fetch) polyfill in a CommonJS module
|
||
|
|
for browserification, and avoids appending anything to the window, instead returning a setup
|
||
|
|
function when `fetch-ponyfill` is required. Inspired by
|
||
|
|
[object-assign](https://github.com/sindresorhus/object-assign).
|
||
|
|
|
||
|
|
When used in Node, delegates to `node-fetch` instead.
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
|
||
|
|
### Browserify
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
const {fetch, Request, Response, Headers} = require('fetch-ponyfill')(options);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Webpack
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
import fetchPonyfill from 'fetch-ponyfill';
|
||
|
|
const {fetch, Request, Response, Headers} = fetchPonyfill(options);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Options
|
||
|
|
|
||
|
|
Where `options` is an object with the following optional properties:
|
||
|
|
|
||
|
|
| option | description |
|
||
|
|
| ------ | ----------- |
|
||
|
|
| `Promise` | An A+ Promise implementation. Defaults to `window.Promise` in the browser, and `global.Promise` in Node. |
|
||
|
|
| `XMLHttpRequest` | The XMLHttpRequest constructor. This is useful to feed in when working with Firefox OS. Defaults to `window.XMLHttpRequest`. Has no effect in Node. |
